Gauntlets of Zen Focus (3.5e Equipment)

From D&D Wiki

Gauntlets of Zen Focus: These adamantium and white gold bracers bear the engraved image of a yin on the left hand and a yang on the right. They grant the wearer an Attack bonus equal to one-half of their current Wisdom modifier rounded down. This effect increases as the character level increases.

The gauntlets are believed to be part of an artifact known as the Full Plate of the Zen Disciple. This artifact is mentioned in legends but no one has seen this artifact in centuries.
